Rondo doubtful against Magic

Rajon Rondo (ankle) is doubtful for Sunday’s game against the Orlando Magic, head coach Doc Rivers said before the game. Stephon Marbury would get the start if Rondo does not play. Rondo slightly sprained his right ankle on Friday night against the Cleveland Cavaliers. He left the game with Celtics trainer Ed Lacerte but later returned to finish with six point and 10 assists.
